RDA definitions (rdadefs)

This module contains BrainVision Remote Data Access (RDA) API definitions, including message structures, type constants and GUID. Refer to the Chapter 12 of the BrainAmp user manual for detailed API description

The module is based on the API implementation (in C) found in the FieldTrip package http://fieldtrip.fcdonders.nl (rdadefs.h)
